| Abstract: |
The planets Gliese (GL) 581 c and d were the first objects which merited a detailed study of their potential habitability. The orbital distances of the two planets have recently been revised. We investigated the habitability of GL 581 c and d under these new conditions with a 1-D radiative-convective atmospheric model, varying the surface pressure and atmospheric composition. GL 581 c was found to be uninhabitable for all scenarios considered. GL 581 d was also found to be uninhabitable for low and medium CO2 atmospheres (3.55·10–4 and 5% CO2 vmr, 1 ≤ psurf ≤ 20 bar). |
